Assisted reproductive technology services are a form of reproductive health services for the community that have developed at this time. One form of implementation of this service is IVF. IVF is a solution for married couples to get offspring, but the process of implementing IVF often fails. This is caused by the age factor of married couples over 35 years, so the quality of egg and sperm cells decreases with age and other reproductive hormone disorders that can also affect the fertilization process in IVF. The purpose of this study is to analyze and reformulate the regulation of assisted reproductive technology, which is just an effort to fulfil the right to reproduce to produce offspring. This research method is focused on legal studies that are not by the times, so empirical juridical research is needed. The data analysis technique used is descriptive qualitative analysis to create the concept of regulatory formulation derived from the results of field research and literature studies. This research results in the formulation of article change on assisted reproductive technology services through IVF and article proposals for judicial review to the Constitutional Court regarding assisted reproductive technology services through Conditional Substitutes. It aims to fulfil the right to reproduction for married couples who want to have children.
